Origin
The Ultimate is BH's answer to the question: how light can an XC hardtail frame be while remaining UCI-legal and race-ready? The Ultimate Evo, tipping the scales at just 820 g, uses the finest Toray T1100 carbon and HCIM moulding technology developed in the Basque Country. The more accessible Ultimate RC (1,050 g) brings the same geometry and Boost spacing to riders who don't need the ultimate weight savings. Both variants have been refined through WorldCup competition feedback.

The verdict

- Evo pricing reaches premium territory for the frame alone
- PF92 BB requires careful installation to avoid creaking
